Welcome to Gaia! ::

I'm making a costume that is going to require a fullbody suit made of a rubber like material, I'm thinking of using neoprene. Has anyone used it before and if so could you please tell me some tips so I don't screw everything up.

I know it's extremely tough to sew with a standard machine and it requires heavy thread, that's about it.

before you go to the time and expense, please check it out thoroughly.

i hear that it quickly gets VERY hot!!

Best thing to do is talk with the ladies at the fabric store ^.^

You got my interest going, so I googled it. And it lead me to the site of the creators of neoprene, which stated

Resists degradation from sun, ozone and weather
Performs well in contact with oils and many chemicals
Remains useful over a wide temperature range
Displays outstanding physical toughness
Resists burning inherently better than exclusively hydrocarbon rubbers
Outstanding resistance to damage caused by flexing and twisting

So it sounds like it won't melt or anything from friction. But I think you basically have to treat it like normal fabric.

Also, I pulled up this thread from cosplay.com that offers some good advice from some cosplay pros
